The Ministry of Infrastructure, Communications and Transport (SICT) has awarded the consortium formed by CICSA and FCC the construction and design of 111 kilometres of the Tren del Norte, on the Saltillo to Santa Catarina section. The project has a budget of over €1.47 billion and a completion period of 31 months.

The Saltillo-Nuevo Laredo Passenger Train is part of the federal government's plan to expand the country's passenger rail network, with the aim of improving connectivity in northern Mexico and facilitating mobility between two strategic industrial hubs.

According to the SICT, this project seeks to reactivate the railway infrastructure in the region, offering new mass transport routes that will benefit both the population and the logistics sector.
